Acron Calculator

Acron Calculator is a full-featured scientific calculator that displays mathematics as it is written, with stacked fractions, radicals, integrals, matrices, and readable expressions. It supports exact arithmetic, roots, powers, logarithms, trigonometry, complex numbers, matrices, unit conversion, statistics, curve fitting, equations, constants, variables, and custom functions.

Choose between a visual expression editor and an RPN stack, both with a scrollable calculation history. The app works offline and keeps calculations on your device. For advanced symbolic mathematics, an optional Wolfram Cloud connector or free self-hosted acron-math-server can handle integration, differentiation, limits, sums, simplification, equation solving, and plotting.
